(See Page 64.)
1. Remove knurled locknut (364B) from top of
shaft (386B). Remove screw (377B) and loosen
screw (378B) to remove micrometer stop dial
(376B). Loosen screw (384B)and slide pointer
block (385B) up on shaft (386B). Remove re
tainer ring (387B) from groove near bottom of
shaft (386B) and slide ring up toward center

feed)counter-clockwise toremove shaft (386B)
from bushing. Remove two screws (382B and
383B) holding bracket (369B) and remove
bracket from shaft (386B). Removing bracket
(369B) allows removal of the quill (200B, page
58) assembly from spindle housing.
2. Raise table to upper limit. Place block of
wood between table and bottom of spindle.
Loosen quill clamp lever (453B, page 66).

To Remove Spindle Housing with Spindle:
Styles 1-A, 1-B.
(See Pages 30, 32.)
1. Proceed as per instructions in paragraphs 1
and 2 under "To Remove V-Belt Housing:
Styles 1-A, 1-B" (page 13) and lift off housing.
2. Remove four nuts (95B,page 30; 135B, page 32).
Pull spindle housing straight out of overarm.
This housing assembly weighs approximately
60 lb. [See Figure 15B.]
When assembling, the tee bolts (96B, page 30;
133B, page 32) could be held in correct posi
tions, in circular slot at end of overarm, by
heavy grease until spindle head is pushed into
place in overarm. [See Figure 15B.] Spiral
gear (11 IB, page 30; 129B,page 32) must mesh
with spiral gear shaft (237B,page 36) as hous
ing is pushed into overarm.
If machine is equipped with a double swivel
adapter, remove spindle housing before at
tempting to remove adapter from overarm.
3. After assembling, the spindle alignment with
table should be checked. [See Figure 16A. ]
Tramming readings on a 10" diameter circle
should be 0.000" at both sides and rear, but
0.001" at front. If readings are not 0.000" at
15
sides, it may be necessary to change zero
line on overarm. If readings are not 0.000"
at rear and 0.001" at front, it may be neces
sary to rescrape head.
